L-carnitine is synthesized from the essential amino acids lysine and methionine. Because approximately 98% of the body's L-carnitine supply is found in muscle mass, and the nutrient needs of active adults outweigh those of inactive people, ON offers this L-carnitine supplement providing 500 mg of pure L-carnitine per 1-tablet serving.
At ON we are proud to know that we are one of the few sports nutrition companies who own and operate their own production facilities. While it's true that ON is one of the world's largest producers of sports nutrition products, we remain focused on being recognized as the best. In fact, our requirements for raw materials are so strenuous that it's not unusual for ON Quality Assurance Technicians to reject entire truckloads of raw materials that do not meet our high standards. We like to think that we take as much pride & care in crafting our award-winning supplements as our consumers do with crafting their physiques and fitness accomplishments.
